Atomic structure of the Ge(101) surface

The atomic structure of the $\mathrm{Ge}\mathrm{}\left(101\right)c(8\mathrm{}\times 10)$ surface is studied in the present paper by means of scanning tunneling microscopy and low-energy electron diffraction. A detailed model of the structure has been proposed for further investigation. The surface consists of zigzag chain atoms, adatoms, dimers, rebonded atoms, and rest atoms arranged at different levels and in different orientations, and thus is even more complicated than the $\mathrm{Si}\left(111\right)7\times 7$ surface.
